Abstract
INTRODUCTION: We describe a case of metallic, angiographic coil migration, following radiological exclusion of a gastroduodenal artery pseudoaneurysm secondary to chronic pancreatitis. PATIENTS AND METHODS: A 55-year-old man presented to the out-patient clinic with chronic, intermittent, post-prandial, abdominal pain, associated with nausea, vomiting and weight loss. He was known to have chronic pancreatitis and liver disease secondary to alcohol abuse and previously underwent angiographic exclusion of a gastroduodenal artery pseudoaneurysm. During subsequent radiological and endoscopic investigation, an endovascular coil was discovered in the gastric pylorus, associated with ulceration and cavitation. This patient was managed conservatively and enterally fed via naso-jejunal catheter endoscopically placed past the site of the migrated coil. This patient is currently awaiting biliary bypass surgery for chronic pancreatitis, and definitive coil removal will occur concurrently. CONCLUSIONS: Literature review reveals that this report is only the eighth to describe coil migration following embolisation of a visceral artery pseudoaneurysm or aneurysm. Endovascular embolisation of pseudoaneurysms and aneurysms is generally safe and effective. More common complications of visceral artery embolisation include rebleeding, pseudoaneurysm reformation and pancreatitis.
